An increasing number of interdependent phenomena on a global scale are analyzed as complex networks: international trade, human mobility, communication and transportation infrastructures are just a few examples. Furthermore, researchers are more and more aware that many of these networks are interrelated and cannot be analyzed in isolation. However, only recently the academic literature has started to develop new methodologies to analyze the dynamics of intertwined networks, including cascading failures and the transmission of shocks across multiple and heterogeneous network structures [1]}, [2]}. We want to contribute to this emerging field of research on multiple networks by analyzing the relationship between the World Trade Web (WTW) and the International Migration Network (IMN).
